问题描述
昨天想整合下springmvc和mybatis，用junit写了个测试，测试过程中，mybatis的mapper无法注入，报BeanCreationException，相关信息大家看下，帮小弟解决下 1 错误堆栈信息 org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'com.hft.dal.mapper.AccountMapperTest': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: private com.hft.dal.mapper.AccountMapper com.hft.dal.mapper.AccountMapperTest.accountMapper; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No matching bean of type [com.hft.dal.mapper.AccountMapper] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency. Dependency annotations: {@org.springframework.beans.factory.annotation.Autowired(required=true)} 2 applicationContext.xml <context:component-scan base-package="com.hft" /> <context:annotation-config /> <tx:annotation-driven /> <bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource" destroy-method="close"> <property name="driverClassName" value="com.mysql.jdbc.Driver" /> <property name="url" value="jdbc:mysql://127.0.0.1:3306/test" /> <property name="username" value="root" /> <property name="password" value="root" /> </bean> <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager"> <property name="dataSource" ref="dataSource" /> </bean> <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean"> <property name="dataSource" ref="dataSource" /> <property name="mapperLocations"> <list> <value>classpath*:com/hft/dal/mapper/*Mapper.xml</value> </list> </property> </bean> <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer"> <property name="basePackage" value="com.hft.dal.mapper" /> <property name="markerInterface" value="com.hft.dal.mapper.MarkerInterfaceMapper" /> </bean> 3 AccountMapper类，MarkerInterfaceMapper是个空接口public interface AccountMapper extends MarkerInterfaceMapper { public List<Account> getAllAccount(); public void addAccount(Account account);}4 junittest类@RunWith(SpringJUnit4ClassRunner.class)@ContextConfiguration(locations={"classpath*:applicationContext.xml"})public class AccountMapperTest extends AbstractJUnit4SpringContextTests{ @Autowired private AccountMapper accountMapper; @Test public void testGetAllAccount() { System.out.println(accountMapper.getAllAccount().size()); } 5 所引入的的包 6 项目目录结构
解决方案
AccountMapper 类没加注解，扫描不到，就注入失败了，http://blog.csdn.net/ydwuli06/article/details/6993219
